I use Yahoo for email, so 99% oif spam is caught in got into a separate 'spam' folder. I check quickly and then delete.

One day about 2 months back I opened on. Scrolled down to the bottom and . . . I was able to UNSUBSCRIBE! Took a look at some others, ditto. Within 3 days my spam mail was down to viagra stuff (no unsubscribe on those).
